A river has a cross-section that is approximately a rectangle 10-ft deep and 50-feet wide. The average velocity is 1 ft/s. How many gallons per minute pass a given point? What is the average velocity (assuming steady flow) at a point downstream, where the channel shaped has changed to 7 ft in depth and 150 ft in width?
